摘要： PROBLEM TO BE SOLVED: To provide a screen 100 that saves energy required to move diffusion particles used for diffusing projection light and reduces scintillation such that occurrence of uneven distribution of diffusion particles on the entire screen is restrained.SOLUTION: A first light diffusion layer 1 provided on the incident side of projection light includes polarized light diffusion particles, a dispersion medium for dispersing light diffusion particles, and a hold member holding for light diffusion particles. The light diffusion particles reciprocate in the dispersion medium by an electric field generated by an AC voltage applied to electrodes 16a and 16b. Thus, a light ray incident on the screen 100 temporally changes the scatter distribution of a scattered wave, formed as a result of passing through the first light diffusion layer 1, and phase, and thereby reduces or removes scintillation. When a voltage is not applied to the electrodes 16a and 16b, light diffusion particles are attracted to the hold member by means of electrostatic force and maintain their positions relative to the screen 100.
